Original change's description:
> [GridNG] Implement alignment within grid-areas.
>
> This patch implements alignment within a grid-item's grid-area.
> When creating the GridItemData we read of the containers, and
> grid-item's style, or determine its alignment axis-edge, and if it
> should be stretched, saving this information on the GridItemData.
>
> When placing the grid-item it will use this to adjust the offset.
>
> This doesn't implement baseline alignment which requires a secondary
> pass to correctly determine the baseline for the column/row.
>
> The other TODO relates to the constraint-space API, and how grid will
> need a slightly new concept in order to do block-axis stretching
> easily. By default non-replaced grid-items will stretch to the available
> space. A new bit on the space can indicate that we should stretch to
> the available space (if possible), this is similar to the shrink-to-fit
> bit we have today.
>
> This adds a self-start/self-end test as after implementing this now new
> tests passed immediately, and I don't believe we had good test
> coverage for inflow content with these keywords.
